This article has examined the effects of magnetic fields with intensities of 1 mT, 3 mT, and 5 mT on two species of cichlid fish (family Cichlidae). This study focused specifically on assessing the influence of these magnetic fields on larval development, the survival rate, and the occurrence of deformities in the larvae of the jaguar cichlid () and the green terror (). The analysis of the study results indicates that the effects of magnetic field exposure depend both on its intensity and on the fish species being studied. Magnetic fields, depending on the applied intensity, can influence changes in body size as well as the size of the yolk sac. In jaguar cichlid larvae, increased survival was observed in the groups exposed to the magnetic field; however, this was accompanied by a higher number of deformities compared with the control group. In the case of the green terror, the highest survival rates were recorded in the control group and in the group exposed to a magnetic field of 3 mT, while increased numbers of deformities were also noted in the exposed groups. The obtained results may be of significant importance for ornamental fish aquaculture, where appropriately selected magnetic field parameters could support larval growth and survival, reducing losses in breeding.
本文研究了强度为1毫特斯拉、3毫特斯拉和5毫特斯拉的磁场对两种丽鱼科鱼类（丽鱼科）的影响。本研究特别关注评估这些磁场对美洲豹丽鱼（）和绿恐怖丽鱼（）幼体发育、存活率以及幼体畸形发生率的影响。研究结果分析表明，磁场暴露的影响既取决于其强度，也取决于所研究的鱼类物种。根据施加的强度不同，磁场会影响鱼体大小以及卵黄囊的大小。在美洲豹丽鱼幼体中，暴露于磁场的组存活率有所提高；然而，与对照组相比，畸形数量也更多。对于绿恐怖丽鱼，对照组和暴露于3毫特斯拉磁场的组记录到最高存活率，而暴露组中畸形数量也有所增加。所获得的结果对于观赏鱼养殖可能具有重要意义，在观赏鱼养殖中，适当选择磁场参数可以支持幼体生长和存活，减少繁殖损失。
